Analysis Steps

• Define the repeating unit cell (RUC)
• Describe the geometric structure of the yarns
  and matrix
• Write the 3-D constitutive equation of a segment
  of the yarn
• and interstitial matrix
• Integrate the above equation over the complete
  volume of the RUC
• The integrated constitutive equation represent
  the average
• equation and deduce all elastic constants
